winc

winc is a CLI tool for spawning and running containers on Windows according to the OCI specification.

Building

Requirements

• Golang
  • Make sure you have set a GOPATH
• Git
• mingw-w64
  • Select x86_64 as the target architecture
  • After install, ensure that gcc.exe is in your PATH

To clone and build winc.exe:

go get -d code.cloudfoundry.org/winc/...
cd $GOPATH/src/code.cloudfoundry.org/winc
go build ./cmd/winc

Testing

Set the following environment variables first:

WINDOWS_VERSION to your version of Windows.

WINC_TEST_ROOTFS to the path to a container image.

GROOT_BINARY to the path of the groot executable to use while running integration test.

GROOT_IMAGE_STORE to the path of the directory that groot uses for layers and the volume.

E.g.

$env:WINDOWS_VERSION="2019"
$env:WINC_TEST_ROOTFS="docker:///cloudfoundry/windows2016fs:2019"
$env:GROOT_BINARY="$env:GOPATH\bin\groot.exe"
$env:GROOT_IMAGE_STORE="C:\ProgramData\groot"
ginkgo -r integration/

To install Ginkgo and run the tests:

go get github.com/onsi/ginkgo/...
cd $GOPATH/src/code.cloudfoundry.org/winc
ginkgo -r -race -keepGoing
